Volunteers are engaging in an underwater harvest, collecting seagrass seeds in a bid to restore vital coastal ecosystems in the south of England. This effort is part of a broader initiative to expand these underwater meadows, which play a crucial role in combating climate change by capturing carbon and supporting marine biodiversity.
The process requires volunteers to identify specific parts of the seagrass plant during low tide. Experienced collectors look for the spathe, a pod-like leaf that is slightly rounder and paler than the darker, flatter blades. The seeds, when ready for picking, are arranged in a neat row, slightly raised from the surface.
"Sometimes, it's just about feeling around and you can kind of feel these short stems that feel like they've got a pack of Tic Tacs in them," said volunteer Sophie Whitemoor. Fellow volunteer James Harper described his technique as "just a case of looking for the most round stems, really." The volunteers expressed enthusiasm for the restoration projects, with Jackie Mellan stating, "It's just a passion for me, really. Any opportunity I can come out and help with restoration projects then I do."
The volunteers work against the clock, as the turning tide eventually forces them to retreat from the shore. The harvested seeds are carefully placed in barrels of cool seawater to be transported for processing. This delicate operation aims to establish new seagrass beds, which are essential habitats for a variety of marine life and act as significant carbon sinks.
Seagrass meadows are known to store large amounts of carbon in their leaves and roots, and in the sediment beneath them. Restoring these areas is considered a key nature-based solution to mitigate the effects of climate change. The health of these underwater meadows directly impacts coastal resilience and marine biodiversity, making the volunteer efforts significant for environmental conservation.
